FHWA Peer Exchange Report on Corrosion Prevention and Mitigation for Highway Bridges

The US Government Accountability Office (GAO) report entitled Highway Bridges - Federal Highway Administration Could Better Assist States with Information on Corrosion Practices (GAO-21-104249) recommended that the Federal Highway Administration's (FHWA’s) ongoing bridge preservation efforts include activities, such as peer exchanges and case studies that focus on addressing the challenges States face with determining the circumstances under which specific corrosion practices and materials are most effective. In response to the GAO report, the FHWA conducted two regional peer exchanges: (1) for the Midwest States which have environments with arid conditions or that experience frequent freeze/thaw cycles and use de-icing chemicals on their highway bridges, and (2) for the Northeast, Southeast, and West States which have environments that experience freeze/thaw cycles or have highway bridges exposed to a saltwater environment. These peer exchanges focused on State practices and materials used that mitigate bridge corrosion. The results of the peer exchanges can be categorized as (1) actions States are undertaking to slowdown, reduce, and prevent corrosion from occurring to their existing bridges and (2) policy changes States are making to their design standards, details, and material specifications to eliminate root causes of corrosion.
